SHEET METAL ROOFING Filed April 11, 1930 Ihuenior.

' S 1 Conner, ,B WWWW Patented May 3, 1932 SOMERVILLE VAUGHN CONNER, OFNEW ALBANY, INDIANA SHEET METAL ROOFING v Application filed April 11,

My said invention aims to provide sheet metal roofing having overlappingchanneled edges of such form that the sheets may be readily andeconomically manufactured, easily laid without danger of being out ofparallelism or alinement, and which, when in assembled position on theroof will have a maximum efficiency in excluding water from penetratingthrough the roofing.

With these and other objects in view the invention includes the novelconstruction hereinafter described and defined by the appended claims.

My invention is illustrated in the accompanying drawings in which Figurel is a sectional view partly broken away showing a pair of roofingsheets in assembled condition as applied to the roof.

Figs. 2 and 3 are separate views (in section) of the individual sheetportions.

Referring by reference characters to these drawings, 1 designates one ofthe sheets and 2 the other. These are shown as having overlappingchanneled portions or corrugations forming the single seam shown, but itwill be understood that the opposite edges of the sheets (which arebroken away) would'be joined to other sheets in a similar manner,

' the number depending on the extent of roof- The sheet is provided withan upstanding channeled portion of inverted truncated V- shape spacedback from the edge or margin of the sheet and comprising reverselyinclined walls 1a and 1b of equal height and surmounted or united atthetop by a flat portion 10. Beyond the bottom of the wall lb is aportion 1d lying in the same plane as the main body ofthe sheet andprovided with an angularly upturned margin or edge 16.

The channeled portion of sheet 2 is also of approximately invertedtruncated V-shape but its flat top is provided with a re-entrantV-shaped portion or channel as and for the purpose hereinafterdescribed.

1930. Serial No. 443,508.

This channel and re-entrant portion comprises a wall 2a designed to restagainst the outer face of wall 1a, and a short or narrow wall 26designed to rest upon the upper portion of the wall 1?), these wallsbeing connectedat the top by a flat portion 20 designed to rest on thefiat top portion 10. The opposite side 2?) of the re-entrant channelterminates in a flat top portion 2d from the edge of which the mainchannel wall 26 extends downward to the main body of the sheet.

Such channel formations are very easily formed by rolling or stampingmethods, and in laying the roofing are easily assembled in exactparallelism or alinement as the inclined walls 2a and 2b guide theoverlying sheet into exact position and hold it perfectly straight dueto the accurate interfitting of the parts.

As the overlying sheet is pressed down, by the nails 3 driven throughthe fiat top portions 20 and 10, the former is pressed down on thelatter while the wall 26 is pressed down against the upwardly inclinededge 16.

The joint thus formed is one which is firmly held and thoroughly bracedand is proof against leakage.

Should water work in under the wall 2a and between surfaces and there-entrant V portion 2b-20 will cause it to be deflected downward intothe channel 165 and be carried out at the bottom of the sheet.

I claim:

A sheet metal roofing comprising an underlying member of generalinverted truncated V shape, having a flat top portion, and having also atrough portion at the lower end of one of its downwardly divergingsides, said trough being formed of a substan- S tially horizontallateral extension, and an upwardly extending terminal flange, and anoverlying section also of general inverted truncated V shape, having atits central upper portion a V shaped groove, one wall of which bearsagainst the same side wall of the underlying member to which the saidtrough portion is connected, the other wall of said V shaped troughspacing the inclined Wall of the overlying member away from the Wall ofthe underlying member, said inclined wall of the overlying member alsocovering the trough at the lower end of the underlying member, saidoverlying member having also a flat portion to rest on the flat portionof the underlying member to receive a nail which passes through bothmembers, said overlying member also having its'other inclined wallfitting against the remaining inclined wall of the underlying member,substantially asde= scribed. V

In testimony whereof, I aflix my signature.

S. VAUGHN CONNER.
